Hybrid inverters are multi-functional devices that are connected to at least the power grid as well as an energy storage system. You can configure them according to your specific preferences, so the inverter will send the energy produced directly to the electrical appliances in your home. If the PV installation produces more energy than is required at the time, the excess energy does not have to be sent to the grid. It is possible to use it to charge an energy storage system. This allows the prosumer to enjoy free electricity after sunset when their PV system is not producing power.
